Abstract
A workpiece having a surface to be metallised is placed in an enclosure. A plasma is produced in a plasma tube which extends into the enclosure, the plasma having a post-discharge zone in which the surface to be metallised is placed. Vapour of a metal carbonyl compound is injected into the enclosure, such compound dissociating in the post-discharge plasma to cause the metal to be deposited on the surface.
